Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Medium to High
Total water use (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water use | --- | 503,769.93 Cubic meters |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 385,551.58 Cubic meters | 503,769.93 Cubic meters |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2015 | June 30, 2016 |
| Baseline Year | July 1, 2004 | June 30, 2005 |
A brief description of when and why the water use baseline was adopted:
The 2005 water baseline was adopted based on its relation to the energy performance contracts completed by Siemens. The baseline is before the energy contracts were implemented.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | ||
| Number of employees resident on-site | ||
| Number of other individuals resident on-site and/or staffed hospital beds | ||
| Total full-time equivalent student enrollment | ||
| Full-time equivalent of employees (staff + faculty) | ||
| Full-time equivalent of students enrolled exclusively in distance education | ||
| Weighted campus users |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 15.27 Cubic meters | 25.61 Cubic meters |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area | 835,591.69 Gross square meters | 465,977.85 Gross square meters |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 0.46 Cubic meters per square meter | 1.08 Cubic meters per square meter |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Yes
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | 144.76 Hectares | 103.19 Hectares |
Total water use (potable + non-potable) per unit of vegetated grounds:
| Performance Year | Baseline Year | |
| Total water use per unit of vegetated grounds | Cubic meters per hectare | 4,881.74 Cubic meters per hectare |
Percentage reduction in total water use per unit of vegetated grounds from baseline:

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
In fiscal year 2016, George Mason University piloted a energy and water reduction campaign within Housing and Residence Life that included reminder prompts to turn off lights, set thermostats, and take shorter showers
A brief description of the institution's water recovery and reuse initiatives:
Water recovery and reuse systems are limited due to concerns of local governing
authorities in certain locations and situations. George Mason University's Child Development Center Garden has an irrigation system from Water Management, Inc. The irrigation system utilizes rainwater to water the garden.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):
Since 2005, Mason has initiated two energy savings performance contracts where heating, ventilation, and air conditioning equipment were upgraded along with lighting and water fixtures. Mason also follows Virginia state policy which states that all new buildings should be built to LEED Silver or equivalent. George Mason University's Design Information Manual also prioritizes water saving infrastructure when constructing new buildings.
